Part 1. How Much Space Does iPhone Backup Take on Computer?

Well, this depends on how much data on your iPhone. If you have 128GB of storage used up on your iPhone, it usually requires more than 128GB of iCloud or computer storage to back up everything on the iPhone. Generally, a full iPhone backup needs at least 7GB of storage space; therefore, before you back up large iPhone data with iTunes, the iTunes default location C Drive must have more than 10GB of free storage left. You can check the iCloud backup file size to estimate the iTunes backup size because iCloud backup is nearly the same as iTunes backup.

Fix 5. Change the iTunes Backup Destination

iTunes says I don't have enough space but I do. By default, iTunes backup is located in the C Drive of the Windows computer. If you store too many files in the C Drive, your computer will run slower and slower, and the C Drive storage will get less and less. Thus, you can change the iTunes backup location to your computer's other partitions. The steps are as below:

Step 1. On your Windows PC, double-click "My Computer"/"This PC" > go to the path "C:\Users\[PC name]\AppData\Roaming\Apple Computer\MobileSync" > cut the whole folder under "MobileSync" to any location you like > right-click and select "Open command window here".

Step 2. Then, input: mklink/J"C:\Users\[PC name]\AppData\Roaming\Apple Computer\MobileSync\Backup" "D:\MobileSync". Press the "Enter" key.

Note: The "D" in the second path means D Drive. If you would like to move the iTunes backup to the E Drive, you can set the second path as "E:\MobileSync". If you cannot find the folder AppData, you can open "Windows Explorer" on your computer > C > click "View" at the toolbar > select "Hidden" items to make it unhidden in the system.
